dc.description.abstract | Combined measurements of soil temperature and electric potential in the upper 15 cm of a glacial sandy-loam soil were made during the winters of 1986-1987 and 19871988 at the University of Michigan Botanical Gardens using an electronic data acquisition system at frequencies varying from 10 min to daily (midnight). Most of the data was collected at hourly intervals.Analysis of temperature-potential time series at two locations with probes at (0, 3, 6, 9) and (0, 5, 10, 15) cm depths indicated that the variation of electric potential relative to the potential of a 1.5 m ground spike could be interpreted as the response of an electrolytic concentration cell without transference formed by a probe and the ground spike. As the electrolyte concentration is much greater at the ground spike, and electric potential varies inversely with concentration, the potentials at the soil probes varied over the range of approximately 300-700 mV in a manner consistent with the behavior of a concentration cell.The rapid and systematic pattern of potential variation during freeze-thaw events demonstrates that the effects of electrolyte concentration and dilution are products of evaporation-distillation, the melting of frost-purified ice, soil water advection to the freezing-evaporating region, concentrated electrolyte expulsion from the freezing region and the infiltration of rain and snow melt waters. | en_US |
